Hmmmm..... Uses a 'relatively large' amount of energy when changing a display that is rarely changed. Solar cell + capacitor sounds like a perfect match!

for the record: it's almost that the actual questions asked today are from people who are commenting on gizmodo for the first time and have never even owned a gadget other than an ipod.

seriously, how many comments are asking "what is e-paper"

dudes, get with the times, the concept for this technology is more than eight years old, either keep up or don't innundate us with your stupid "don't want to use google" babble.

This is similar to the BiNem® technology.

LCD technology is literally twisted to get 2 zero-power stable states

Cholesteric LCDs have been around for years. Better fidelity now, maybe, but meh for now.

i like the idea of digital photo frames, i dont like the idea of them being bright like a computer screen when the room is dark, having them plugged in with an unsightly cord, and sitting there wasting energy.... something like this could have a battery, used only when you are changing the image, and the rest of the time it would sit there like a picture frame

The Sony e-reader simply uses very very small little balls that are half black and half white.

An electrical charge switches which side of the ball that is facing the viewer. Millions of these little balls align to produce your image.

Now, with color displays, I'd assume you have balls that are shaded CMYK, and they are showing different sides of the ball to the viewer, the combination of many of these balls, all showing certain shades, gives the impression of a solid block of color when viewed from a difference, much like a pointillism image by Seurat.

However, note that the black and white explanation is fact.

The color explanation is me speculating.

Epaper uses no power except when the image changes, so it is a great way to display a book, where you have a static page and only change it a few times a minute or so depending on your reading speed.

Epaper also does not require any backlighting to see during bright lights. It basically looks and functions like paper. The lack of this light also makes epaper VERY easy on the eyes.

Epaper also can be seen from large angles, it does not vanish from certain angles like normal lcd tech.

Now, if you want to know the science behind it, I have no idea.

But the point is that it is like a piece of paper in terms of easy viewability and eyestrain, but it can be changed at will like an lcd screen.

@burnt2acrisp: ePaper is what you use to smoke your eWeed, of course.

Don't forget potential use at gas stations. Prices going up and down all the time.

I still don't understand ePaper. It seems a lot like LCD technology, no? Is it a power-consumption issue? That is, ePaper can retain the image even after power is cut?

With the advent of wireless power, doesn't that make it a bit moot?

I guess I need a "Giz Explains"...

@J0hnP: Here's a quick way to think of epaper: think electronic etch-a-sketch.

I'd be interested to learn what "relatively large" is in terms of energy usage.
